A disjunct in the linguistic landscape: Messages about food and nutrition in Indonesian school environments

In Indonesia’s schoolscapes, messages regarding food and nutrition abound. The researchers conducted descriptive, evaluative research on the nature and scope of the linguistic landscape around 20 primary school grounds in Jakarta and Depok education districts. The purpose of this study was to gather (digitally) and analyze food/nutrition signs/texts in order to determine which languages are represented in which places, and the kinds of messages for each language. As well, the study explored other non-food images relating to health found in these schoolscapes. Data were analysed using open and axial coding. The study found that the majority of the texts and images are found to be in Indonesian and only a small percentage are in Sundanese, Arabic, Japanese and English. Texts relating to food and nutrition were found inside and outside the school environments. Each language was responsible for a particular type of message. Official (top down) messages inside the schoolscapes advocate for healthy food and nutrition. Texts found outside the schoolscapes convey a variety of messages, healthy and otherwise: from food labels, and flavor, to cigarette advertising. There is a ‘disjunct’ between the overtly health-oriented linguistic landscape inside the school perimeter and the less healthy linguistic landscape outside the schoolscapes, an issue which may be of concern to schools and their communities

Epithelioma of Malherbe: new ultrasound patterns

<p>Abstract</p> <p>Backround</p> <p>Calcifying epithelioma of Malherbe, or Pilomatricoma, is considered an uncommon cutaneous neoplasia, normally occurring in children as a solitary, firm, asymptomatic, hard, subcutaneous, slowly growing nodule on the face, neck, or proximal upper extremity. In literature, two Pilomatricoma ultrasound patterns are described: the totally calcified nodule and the hypoechoic nodule with internal calcific foci. High frequency ultrasound has not yet been applied for routine diagnosis of Pilomatricoma. The aim of the study was to retrospectively identify specific ultrasound features.</p> <p>Methods</p> <p>We retrieved 124 histologically Pilomatricoma cases: 28 patients with 32 lesions were preoperatively evaluated with ultrasound.</p> <p>Results</p> <p>22/32 have shown a solid formation, hypoechoic, with a sharp outline. Of these 22, 10 lesions were completely calcifying and 12 partially calcified. In 3/32 lesions with uncertain diagnosis, ultrasounds showed a complex/mixed pattern with pseudo-fluid areas and microspots. 7/32 lesions with US different diagnosis included 3 complex lesions, 2 cystic lesions and 2 solid nodular lesions.</p> <p>Conclusion</p> <p>In addition to well-known ultrasound patterns (completely calcified and partially calcified) we identified three new, not yet described, patterns that constitute the 31% of the cases: complex, pseudocistyc and pseudotumoral.</p

Preparing Teachers through International Experience: A Collaborative Critical Analysis of Four Australian Programs

In an increasingly internationalized, interconnected and globalized world, characterized in many school education contexts by diverse classrooms and varied student needs, the importance for teachers to develop an intercultural competence has become urgent. International experiences, embedded within teacher education, are seen as one means to enhance this capability. In this Australian study, coordinators of international professional experiences from four NSW universities discuss and interrogate the strengths and weaknesses of their own and each other’s programs, guided by an established evaluation framework for such programs. Findings indicate that, while support for such programs is strong in the lead-up to and during such international experiences, subsequent evaluation of these programs and reflection remain underdeveloped. Implications for international professional experience programs are discussed

Beta adrenergic receptor activation attenuates the generation of inositol phosphates in the pregnant rat myometrium. Correlation with inhibition of Ca++ influx, a cAMP-independent mechanism.

International audienceIn the pregnant rat myometrium, an averaged 30% of inositol phosphate accumulation induced by carbachol and oxytocin was inhibited by oxodipine indicating that a part of receptor-mediated generation of inositol phosphates depended on Ca++ influx through voltage-gated Ca++ channels. In fura-2-loaded cells, carbachol and oxytocin caused a two-phase [Ca++]i response, made up of a transient [Ca++]i peak of about 700 nM followed by a sustained phase of about 120 nM. Oxodipine reduced the [Ca++]i peak by 40% and the plateau phase by 50%, pointing to a contribution of Ca++ influx in both the [Ca++]i peak and sustained phase. Isoproterenol reduced inositol phosphate response to carbachol and oxytocin to an amount equivalent to that elicited by oxodipine. No additional reduction could be obtained in a combination of isoproterenol and oxodipine. Isoproterenol decreased by 40% the [Ca++]i peak and by 70% the [Ca++]i plateau phase. Differently from isoproterenol, forskolin did not affect inositol phosphate accumulation induced by oxytocin and failed to attenuate the [Ca++]i peak. The inhibitory effect of isoproterenol on both inositol phosphate accumulation and [Ca++]i increase induced by oxytocin was abolished by pertussis toxin. These data suggest that beta adrenergic receptor activation is linked via a cAMP-independent, pertussis toxin-sensitive process to an activation of K+ channels, as revealed by use of selective K+ channel antagonists, with the consequent closure of voltage-gated Ca++ channels, resulting in the inhibition of the Ca(++)-associated generation of inositol phosphates
